Garnet materials for li secondary batteries and methods of making and using garnet materials

Composites of lithium-ion-conducting ceramic and polymeric materials make superior separators and electrolytes for use in lithium batteries. The ceramic material provides a high conductivity pathway for lithium-ions, enhancing the properties of the less conductive polymeric material. The polymeric material provides flexibility, binding, and space-filling properties, mitigating the tendency of rigid ceramic materials to break or delaminate. The interface between the polymer and ceramic can be made to have a low ionic resistance through the use of additives and coatings.
